ARTIEIGIA.L new]: AND nanivnssrneauroa To all wit m it may 00n0e7'm- Be it known that I, IGNAOE L. Boson, a citizen "of the United States, residing at liuntington, in the county of Gabell and State of West Virginia, have invented-new and useful Improvements in Artificial- Hands and Harness Therefor, of which the following is aspecification.

. My present invention pertains to artificial hands and harnesses therefor; and it has for one' of its objects to provide an artificial hand embodying a friction-creating pro tubera'nce' through the medium ofwhich .the

wearer of the hand is enabled todra'w ar ticles of various kinds toward himself.

Another object is the provision of an artific'ial hand embodying a carrying hook so manipulate the hand with great facility.

' Other objects and practical advantages 1 will be fully understood from the 'following description and claims when the same are read in con unction with the drawmgsaccompanying and forming part of this specification, in which: 1

Figure l is a view showing in proper relation my novel hand and harness.

Fig. 2 is a side elevation of the hand. Fig.3 is an inverted plan view of the same.-

Fig. 4 is a detail section illustrative of the from this it follows that when it is desired to friction-creating protuberance on the lower jaw of the hand. I

Fig. 5 is a plan view of said aw illustrating the groove therein for the secure holding of a pencil, pen or the like.

Similar numerals of reference designate corresponding parts in all'of the views of the drawings. 7 v

The lower jaw l of my novel artificial hand is carried by a shank2 which is provided .at 3 with a bifurcated standard in which is pivoted at 4 the upper jaw 5 of the hand. Suitably fixed in and depending from the forward portion of the jaw 1 is a pad or protuberance 6, of rubber or other friction-creating material. a By virtue of this provision it will be manifest that the wearer of the hand is enabled by pressing the protuberance 6 downwardly upon sheets of I Specification of Letters Patent.

paper or the like to frictionally engage the said protuberance 6 with the sheets of paper so that the sheets may be conveniently drawn toward or pushed from the wearer. In't'he preferred embodiment of the invention, the

protuberance 6 and the complementarybore are of even diameter throughout as shown in Fig. 4:, and hence the protuberance may be readily placed in and removed from the socket, though there is little liability of the protuberance being casually displaced when the hand is inuse. At-the upperside of its forward portion the jaw 1 is. serrated,- as indicated-by 7, 311C113 provided with a-g-roove 8 ells-posedand tapered as shown with a 'viewto' enabling the jaw 1 to's'ecurely hold" a pencil in position, for convenient manipulation through the medium of the artificial hand. The forward portion of the jaw 5 is adapted to cooperate with the forwardportion of the jaw 1 in the holding of a pencil and other articles, and the portions of the jaws in rear of the forward portion are preferably, though not necessarily, shaped as best shownin 'Figsjl' and 2. The jaw 5 is in the form of a lever, and its rear arm E/ is suitably connected with a controlling cable 10, said-cable being by preference partly of chain and partly ofstrap, the strap indicated by 11 being by preference connected through the medium of a snap hook 12 with the rear end of the chain. It will also be readily un derstood lay-comparison of Figs. 1,2 and 3 that'the jaw 1 i's-equipped witha hook 13 for the convenient carrying of buckets and other receptacles; The "said" hook 13' is hinged at 14 to theside of the jaw 1, and

insert the artificial hand into a pocket, or is otherwise desired to use the hand without entailing employment of the hook 13, the said hook 13 may be swung upwardly against and parallel to the standard 3 as shown in full lines in Fig. 2 and by dotted lines in Fig. 3. The hook 13 is shown in its working position in Fig. 1, and it will be observed that the said hook may be easily engaged with V wearer. This sleeve member 16 is provided of the cable 1O.

with opposite arms 17 which are hinged at 18 to arms 19 or the socket member to provide for the necessary flexing of my im-=- provement. At 20 and coincident with the flexing, andby reference to'Fig. lit will be noticed that the sleeve 16 is connected to the ends of astrap yoke 22 which is designed to straddle the adjacent shoulder of the wearer. Manifestly when a heavyv article such as a bucket of water or a suitcase is carried on the hook 13 of the artificial hand, the yoke 22 will serve to impose the said weight on the shoulder of the wearer and will preclude the possibility of the socket member 1.5 and the sleeve member 16 moving downwardly in the sleeve of the I carried bythe latter.

wearer. vAgain it will be observed that the. yoke 22 suspends and carries the sleeve 16,-

the socket member 15 and the artificial hand At 23 is a yoke which is designed to receive the opposite shoulder of the wearer,

V and at 24 is a strap which efiectspermanent connection of the yokcs 22 and 23." The said strap21 extends across at the back of the base of the neckwhich is advantageous inasmuch as it leaves the front portion of the 7 body of the wearer entirely free from pressure. I I

The strap portion 11' of the controlling cable 10 is designed 'to be passed over the first-named shoulder of the wearer and to be carried from said point across the back of the wearer to the point 25 indicated by dotted linesin Fig. 1, where it is permanently attached to the holding portion of the harness. The said point 25.is located ad- -the j aws 1 and 5 together.

.claim and desire to secure jacent to the shoulder loop 23. AtQGfBig. 3, is the usual spring for yieldingly holding By reference-to .Fig. 1 it will be understood that the strap-11 is carried around the first-named shoulder of the wearer.

From this it follows that whenthe said strap ispositionedas illustrated in Fig. 1, forward movement of the artificial hand by the wearer willbe attained by opening of the jaws land 5, while when the wearer relaxes the said shoulder and permits the strap 11 to ride up on theshoulder, the artificial hand may be extended without opening of the jaws. I would also have it .unde'rstood thatby manipulating the shoulder mentioned the wearer may through the medium, of the strap 11 nicelycontrol the jaws 1 and 5. ,Againlwouldhave it under? stood that by reason of the connection of the yoke 23 with'the strap 11', the wearer, by manipulating his left shoulder, en-

abled to nicely control the jaws 1 and 5without entailing any movement whatever of the Y right shoulder.

Having. described .my. invention, what I s y Letters-Patnt,

1. An artificial hand comprising jaws; means for yieldingly. holding the jaws together, and a lateral hook hinged to one of the jaws and adapted when not in use to be folded parallel .to the remainder of the hand. 2. In an artificial hand, thecombination of jaws one of which has a bore at an angle to its outer side, a pad disposed insaid bore and projecting laterally from the outer side of thejaw; said-pad being of friction-creating material, and means for yieldingly holding the aws together.
